AlphaSphere — AI market analyst & trading copilot for retail investors
An AI trading copilot that connects to your existing brokerage, analyzes the market in real time, and gives you plain-English trade recommendations matched to your risk appetite. No emotions, just the plan.
What AlphaSphere does
- Live brokerage first. Connect any major brokerage through SnapTrade and trade alongside the AI — or practice in the free paper-trading sandbox. AlphaSphere never asks for your brokerage password.
- Sphere AI analyst. Ask anything about the market in plain English. Sphere AI pulls live quotes, options chains, news, and sentiment, then answers with the data to back it up.
- Trade signals with receipts. Entry, stop-loss, and staged take-profit levels for stocks and options, each with rationale and backtest context.
- Portfolio health. One source of truth for portfolio value, day change, options marks, risk score, and 1-year performance versus SPY.
Built for trust
Every AI signal is committed to a public, tamper-evident ledger before it is announced, so outcomes cannot be rewritten. The full paper track record — every signal, position, and outcome since June 2026, using only real OCC option contracts — is published at alphasphere.trade/trust.
For developers and agents
AlphaSphere exposes a versioned public REST API with an OpenAPI 3.1 spec, RFC 9239 rate-limit headers, an official CLI, and machine-readable resources (llms.txt, markdown content negotiation on every key page).
